Description

Technical Field

[0001] This utility model relates to the field of cable stripping technology, and in particular to a cable stripping device. Background Technology

[0002] A cable consists of one or more mutually insulated conductors and an outer insulating protective layer. Before use, the outermost insulating protective layer needs to be stripped from the cable's ends to facilitate the connection of the multiple conductors in the middle to the designated positions.

[0003] Most existing cable stripping methods involve using a knife to cut the outer insulation layer of the cable. Since cables are cylindrical, their surfaces lack leverage points. When encountering cables with hard outer insulation layers, it is difficult for operators to use the tip of a knife to cut through the cable's outer insulation layer. Utility Model Content

[0004] This invention provides a cable stripping device that solves the technical problem that existing blades are difficult to cut through the hard outer insulation layer of cables.

[0005] To achieve this technical objective, the present invention adopts the following solution: a cable stripping device, comprising a main body and a cutting component;

[0006] The main body is cylindrical, and a through hole for accommodating cables is opened in the middle of the main body;

[0007] The cutting assembly is retractable and mounted on the main body for cutting the outer sheath of the cable.

[0008] Furthermore, an annular receiving groove coaxial with the main body is provided on the side wall, and a receiving cavity for installing the cutting component is provided at the bottom of the receiving groove.

[0009] Furthermore, the receiving cavity is provided with a square clearance groove that connects the interior of the receiving cavity and the through hole, and the clearance groove extends along the axis of the main body.

[0010] Furthermore, mounting holes are provided on both sides of the clearance groove. The mounting holes extend radially along the main body. The mounting holes are provided with clearance holes that connect the mounting holes and the receiving cavity. The clearance holes and the mounting holes are coaxially arranged, and the diameter of the clearance holes is smaller than the diameter of the mounting holes.

[0011] Furthermore, the cutting assembly includes a pressure block, screws, blades, and springs;

[0012] The pressure block is embedded in the receiving cavity, and the side of the pressure block located outside the receiving cavity is an arc surface, which is coaxial with the main body;

[0013] The tail of the screw is threadedly connected to the pressure block, the head of the screw is slidably set in the mounting hole, and the screw shank near its head is slidably set in the clearance hole.

[0014] The blade is fixed on the pressure block, and the blade is slidably set in the clearance groove;

[0015] The spring is fitted onto the screw rod, with its two ends abutting against the pressure block and the receiving cavity, respectively.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention features a cutting assembly. During cable stripping, the cable is first inserted into the through-hole, then the pressure block is pressed down with a finger. The pressure block compresses the blade, causing it to pop out of the limiting groove and make contact with the cable's outer insulation layer. Pulling the cable then cuts through the insulation layer. Throughout the stripping process, the blade always faces the cable, and there is no risk of sudden blade displacement, preventing injury to workers. This design is safe and convenient.

[0024] To fully understand the purpose, features and effects of this utility model, the following specific embodiments will be used to describe this utility model in detail, but this utility model is not limited thereto.

[0025] like Figures 1 to 4As shown, the present invention provides a cable stripping device, comprising a main body 1 and a cutting component 2. The main body 1 is cylindrical, and a through hole 11 for accommodating a cable is formed in the middle of the main body 1, the through hole 11 extending along the axial direction of the main body 1; an annular receiving groove 12 coaxial with the main body 1 is formed on the side wall of the main body 1, and a receiving cavity 13 for installing the cutting component 2 is formed at the bottom of the receiving groove 12. A square clearance groove 14 is formed in the receiving cavity 13, connecting the interior of the receiving cavity 13 and the through hole 11, the clearance groove 14 extending along the axial direction of the main body 1.

[0026] Please refer to Figure 1 and Figure 4 Mounting holes 15 are provided on both sides of the clearance groove 14. The mounting holes 15 extend radially along the main body 1. The mounting holes 15 are provided with clearance holes 16 that connect the mounting holes 15 and the receiving cavity 13. The clearance holes 16 and the mounting holes 15 are coaxially arranged. The diameter of the clearance holes 16 is smaller than the diameter of the mounting holes 15.

[0027] The cutting assembly 2 is telescopically mounted on the main body 1 for cutting the outer sheath of cables. The cutting assembly 2 includes a pressure block 21, a screw 22, a blade 23, and a spring 24. The pressure block 21 is embedded in the receiving cavity 13, and the side of the pressure block 21 located outside the receiving cavity 13 is arc-shaped, with the arc-shaped surface coaxial with the main body 1; the tail of the screw 22 is threadedly connected to the pressure block 21, the head of the screw 22 is slidably mounted in the mounting hole 15, and the screw shank near its head is slidably mounted in the clearance hole 16; the blade 23 is fixed on the pressure block 21, and the blade 23 is slidably mounted in the clearance groove 14; the spring 24 is sleeved on the screw shank of the screw 22, and both ends of the spring 24 abut against the pressure block 21 and the receiving cavity 13, respectively.

[0028] In its natural state, the spring 24 is compressed and tends to push the pressure block 21 out of the receiving cavity 13. Since the pressure block 21 is connected to the screw 22 and the head of the screw 22 is located in the mounting hole 15 and the head of the screw 22 cannot enter the clearance hole 16, this ensures that the pressure block 21 cannot leave the receiving cavity 13.

[0029] In use, first insert one end of the cable into the through hole 11. Then, the operator places their thumb and middle finger into the receiving groove 12, allowing these two fingers to press against the pressure block 21. Pressing the pressure block 21 moves it into the receiving cavity 13, compressing the spring 24. Simultaneously, the pressure block 21 causes the blade 23 to extend from the relief groove 14, contacting the cable's outer insulation layer. Then, using the other hand, pull the cable, allowing it to slide within the through hole 11, thus stripping the cable. After stripping, release the main body 1. Under the restoring force of the spring 24, the blade 23 springs back into the relief groove 14, preventing injury to the operator.

[0030] The side of the pressure block 21 that contacts the finger is curved, which improves the comfort of the operator's fingers. The receiving groove 12 prevents the operator's fingers from slipping out.

[0031] It should be noted that, under normal conditions, the depth of screw 22 in mounting hole 15 should be greater than the depth of blade 23 in relief groove 14, so as to ensure that when blade 23 contacts cable, the head of screw 22 does not contact cable.

[0032] The number of cutting components 2 can be selected according to actual needs. Multiple cutting components 2 can be arranged at equal intervals along the circumference of the main body 1. In this embodiment, two cutting components 2 are included.

[0033] Finally, it should be noted that the above-listed embodiments are merely preferred embodiments of the present invention. Of course, those skilled in the art can make modifications and variations to the present invention. If such modifications and variations fall within the scope of the claims of the present invention and their equivalents, they should be considered as being within the protection scope of the present invention.
